This application claims the benefit of U.S. Provisional Application No. 62/694,968, filed Jul. 6, 2018, the content of which is expressly incorporated herein by reference in its entirety.

BACKGROUND

The need for efficient and effective systems to classify and cluster data arises in many fields, including data management, science, finance, engineering, environmental monitoring, water supply systems, climate studies, health care, and many other areas of human activity. For example, many fields data involve collecting and analyzing large scale, complex datasets at high velocity “big data.”). Big data may involve datasets of such vast scale that spotting trends or outcomes requires advanced application of analytic data science or knowledge processing (e.g., artificial intelligence). Classification and clustering needs arise for all types of data (e.g., text data, numeric data, image data, video data, etc.).

Conventional methods may include training machine learning algorithms, including neural network models, to predict or classify data. Conventional approaches typically include training and implementing an individual machine learning model. However, an individual model may reach an inaccurate result because the model may not be well-suited to the information it is attempting to classify, or it may lack appropriate training data (e.g., it may classify inaccurately a photo of a cat as a “rat.”). Further, an individual model may reach a sub-optimal result by failing to recognize distinguishing features of a data sample that indicate the data sample optimally belongs in an additional category or a sub-category (e.g., by sub-optimally classifying an image of a hairless cat as a “cat”).

Some conventional approaches may include training and implementing a plurality of models to classify and/or cluster data. For example, a data system may train and implement different models individually to classify and/or cluster data. However, training models individually may inefficiently waste resources. Such an approach may fail to take advantage of comparative strengths of various models. For example, one model may perform better when classifying faces, while another performs better when classifying animals, but when classifying images that includes humans and animals, a conventional approach may simply train the two models individually to cluster data without allowing the models to learn from each other.

For example, as shown in FIG. 2, a conventional approach to classifying a data sample may include using classification models that comprise machine learning models or other classification models. One or more classification models (e.g., classification models 204 a, 204 b, 204 c, 204 d, and 204 n), may be configured to receive input data (e.g., an input data sample 202 such as an image of a hairless cat) and return corresponding classification results (classification results 206 a, 206 b, 206 c, 206 d, and 206 n). A classification result may include a label (e.g., cat, dog, rat, etc.). Classification models may be configured to perform object recognition and classification to detect and classify, for example, animals in images. Classification models may use similar or may use different classification algorithms from each other.

FIG. 2 illustrates problems and challenges associated with conventional approaches to data classification and data clustering. For example, classification models of method 200 may produce different classification results for the same data sample, resulting in misclassification inaccurate classification) or sub-optimal classification. A system may be unable to determine which classification results are accurate and may waste resources by training classification models with sub-optimal training conditions.

As shown, some classification models of FIG. 2 inaccurately classify the input image as depicting a rat or a naked mole rat. In some cases, classification models may sub-optimally classify the input image as cat but not the more optimal classification of a hairless cat. In the conventional approach depicted in FIG. 2, it may be inefficient or infeasible to train the plurality of models to generate an accurate and optimal classification. Further, traditional metrics of classification model output, such as a confidence interval, may provide, incomplete information or may not correlate with a true classification. That is, traditional metrics may not indicate how well a classification model performs as compared to another classification model. In the example of FIG. 2, each classification model may report a high confidence level, for example, but only classification models 206 a and 206 d produce accurate results, and classification model 206 a performs sub-optimally as compared to classification model 206 d. Thus, the high confidence level may not reflect a true classification and it may be difficult to compare results.

Inaccurate and/or suboptimal classifications may arise in conventional approaches to classification. In conventional approaches, a classification model may be trained individually to meet performance criteria when learning to classify data (e.g., trained to minimize a loss function). Classification errors may arise, for example, when an individual classification model converges on a suboptimal number of classification categories during model training. During training, an classification model may reach a local minimum but fail to reach a global minimum of an optimization function. Some classification model may perform better than other classification models on some data samples. Hence, there is a need for unconventional approaches that improve the accuracy and efficiency of individual classification model classification results by learning from and incorporating the results of a plurality of classification models.

Therefore, conventional approaches suffer from inaccuracies and wasteful inefficient use of computing resources. In view of the shortcomings and problems with conventional approaches to clustering data, there is a need for unconventional approaches that improve the accuracy and efficiency of classification and, clustering results by learning from and incorporating the results of a plurality of models.

That is, the container instances do not permit access from outside using terminals or remote shell tools like SSH, RTP, FTP, or CURL, for example. Further, terminating container instances may include destroying data, thereby protecting sensitive data.

FIG. 3 illustrates method 300 for clustering data using a meta-clustering model, consistent with disclosed embodiments. As compared to conventional approaches, method 300 may produce more accurate results with greater efficiency. As shown, method 300 may include using a meta-clustering model 308 to generate a final data cluster based on preliminary data clusters (i.e., preliminary clustered data) which were generated by a plurality of embedding network layers that implement a plurality of clustering methods. By learning from a plurality of individually-trained models and/or embedding network layers, meta-clustering model 308 may advantageously identify more accurate classifications and/or clusters where traditional metrics, such as confidence levels, may provide incomplete information. Clusters may include information relating to nodes of an embedding network layer. For example, a cluster may include a vector of weights associated with nodes of a layer. A cluster may be grouped by an aspect of a latent space generated by an embedding network layer based on a data sample. In some embodiments, meta-clustering model 308 may reduce the dimensionality of clustered data produced by embedding layers, leading to improved accuracy and efficiency. Meta-clustering model 308 may quickly identify an optimal number of data clusters. Accordingly, method 300 provides advantages by increasing accuracy, lowering costs, and reducing resource use hen clustering data. FIG. 3 is provided for purposes of illustration only is not limiting on the embodiments.

Referring to FIG. 3 in greater detail, method 300 may include using a plurality of embedding network layers 304 a, 304 b, 304 c, 304 d, and 304 n to classify and cluster data 302. Method 300 may include generating a plurality of preliminary data clusters 306 a, 306 b 306 c, 306 d, and 306 n corresponding to embedding network layers 304 a, 304 b, 304 c, 304 d, and 304 n. Method 300 may include using meta-clustering model 308 to generate final data clusters 310 (i.e., final clustered data) based on preliminary data clusters. As one of skill in the art will appreciate, method 300 may include any number of embedding network layers, data, preliminary data clusters, meta-clustering models, and/or final data clusters, including more or fewer than those depicted in FIG. 3.

Data 302 may include any kind of data (e.g., text data, image data, numeric data, time series data, etc.) Data 302 may include multi-dimensional data Data 302 may be organized according to any data schema. Data 302 may include a plurality of data samples (e.g., a plurality of image files, a plurality of video files, a plurality text files, a plurality of data columns, etc.). Data 302 may include a number of dimensions (e.g, two-dimensional data, three-dimensional data, four-dimensional data, etc.).

Embedding network layers 304 a, 304 b, 304 c, 304 d and 304 n may be configured to accept data as input and return a data classification and/or data clusters as output. As shown, embedding network layers 304 a, 304 b, 304 c, 304 d and 304 n may be configured to generate a plurality of corresponding preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n based on data 302. Generating preliminary data clusters may include sampling data 302. Generating preliminary clusters may include generating clusters based on node output of a layer (e.g., a vector of weights, activation function values, etc.). Embedding network layers 304 a, 304 b, 304 c, 304 d may include any type of embedding network as described herein and/or any other machine learning model.

Preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n may include data clusters represented as a node-edge diagrams in FIG. As shown, FIG. 3 represents nodes as discs. A node may include data samples that share a classification (e.g., a tag) and the size of the disc may indicate a relative size the node (i.e., the relative amount of data that belongs to the node). FIG. 3 represents edges as lines between nodes. An edge may be based on a relationship between nodes. For example, edge data may be based on a similarity metric between data samples, on a hierarchical relationship (e.g., a data lineage, a parent-child relationship), and/or on any other relationship. The distance between nodes represent aspects of data relationships between the nodes (e.g., the strength of a relationship, the similarity of data, etc.). Although FIG. 3 depicts node-edge diagrams, embodiments may include data clusters organized and/or represented according to any known classification method (e.g., data table, a relational database, a tree diagram, or a vector diagram). In some embodiments, a node of a cluster may include a data sample grouped by an aspect of a latent space of a layer. In some embodiments, preliminary data clusters may have a number of dimensions (e.g., two-dimensions three-dimensions, four-dimensions, etc.). A number of dimensions of preliminary data clusters may be the same as a number of dimensions of data 302. In some embodiments, one or more layers of an embedding network may generate preliminaly data clusters having the same number of dimensions.

As shown by way of example, individual ones of preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n have a corresponding number of clusters, k, whose value is 4, 3, 4, 5, and 3, respectively. Hence, the number of clusters generated by one embedding network layer may be the same as or different from another embedding network layer.

In addition, individual ones of preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n may generate node-edge relationships which may differ from or which may be the same as one another. For example, embedding network layers 304 b and 304 n classify data samples of data 302 in the same way as each other and generate the same edge relationships between data samples to generate identical preliminary data clusters 306 b and 306 n. As another example, preliminary data clusters 306 a, 306 b, 306 c, and 306 d may differ from each other because their respective embedding networks generate different classifications (nodes) and different edge relationships from each other. As compared to the illustration of FIG. 3, method 300 may include other preliminary data dusters which may be the same or different from each other.

Meta-clustering model 308 may include a machine learning model. For example, meta-clustering model 308 may include a deep learning model, a neural network model, an RNN, a CNN, a random forest model, a Support Vector Machine (SVM) model, a Density-based spatial clustering of applications with noise (DBSCAN) model, a k-means clustering model, a distribution-based clustering model, a k-medoids model, and/or any other type of machine learning model. Meta-clustering model 308 may be trained to generate data clusters based on data clusters produced by embedding network layers.

In some embodiments, meta-clustering model 308 may be configured to encode preliminary data clusters 306 a 306 b, 306 c, 306 d, and 306 n. For example, meta-clustering model 308 may perform a principal component analysis (PCA), an independent component analysis (ICA), a non-negative matrix factorization method (NMF), a Factor Analysis (FA), and/or any other algorithm to reduce dimensionality of latent variable generated by a model based on data samples of preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n. Encoding may include implementing an autoencoder (e.g., a variational autoencoder) model. By encoding preliminary data clusters, meta-clustering model 308 may reduce the complexity of the preliminary data clusters and more efficiently produce final data clusters 310.

In some embodiments, meta-clustering model 308 may be configured to generate a data map of data 302 based on preliminary data clusters 306 a, 306 b, 306 c, 306 d, and 306 n. In some embodiments, generating a data map may be unsupervised. In some embodiments, generating a data map may include tracking data samples in a plurality of preliminary data clusters and determining relationships between the data samples. For example, meta-clustering model 308 may learn to predict the frequency with which two or more data samples appear in a same preliminary data cluster and generate a data map based on the predictions. In some embodiments, meta-clustering model 308 may generate a data map based on encoded preliminary-data-clusters (e.g., based on principal components of the preliminary data clusters). A data map may include a plurality of data points in a latent space representing transitions of a data sample between the embeddings. An embedding layer may convert a data sample into a latent space, and a data map may include a visual representation of a data conversion into a latent space. A data map may be based on weights of an embedding layer.

In some embodiments, generating a data map may be supervised. For example, generating a data map may include providing data samples to a user and receiving user feedback. Meta-clustering model 308 may identify a conflict between preliminary data clusters (e.g., embedding network layer 304 a may classify the same data sample differently from embedding network layer 304 b), and meta-clustering model 308 may request user feedback based on the conflict.

In some embodiments, meta-clustering model 308 may determine a performance metric of one or more embedding network layers. For example, meta-clustering model may determine a performance metric of an embedding network layer based on an intra-cluster variance of preliminary data clusters generated by the embedding network layer. in some embodiments, generating a data map may be based on a performance metric.

In some embodiments, meta-clustering model 308 may determine a number of clusters based on a data map and/or a performance metric. Determining a number of clusters may be based on relationships (e.g., edge relationships) between data clusters. In some embodiments, meta-clustering model 308 is trained to determine a number of clusters that optimizes a property of clustered data (e.g., trained to optimize a measure of variance of a cluster a ratio of intra-cluster variance to inter-cluster variance, etc.) Determining a number of data clusters may include implementing methods such as a k-means algorithm, a k-medoids algorithm, an elbow method, an X-means clustering method, an information criterion approach, a silhouette method, a cross-validation method, a method based on a kernel matrix, and/or any other methods of determining a number of clusters in data. In some embodiments, meta-clustering model 308 limits and/or reduces a number of layers of an embedding network to lead to greater processing efficiencies.

In some embodiments, meta-clustering model 308 may generate final data dusters 310. In some embodiments, meta-clustering model 308 may generate final data clusters based on a data map (e.g., the final data clusters 310 may be the same as the data map). In some embodiments, generating final data clusters 310 may include updating one or more embedding network layers by training the embedding network layers based on a number of clusters (e.g., a number of clusters determined based on a data map). In the example of FIG. 3, a final data cluster has a number of final data clusters, k, whose value is 7. In some embodiments, the number of final data clusters may be based on a relationship between clusters of preliminary data clusters. In some embodiments, a number of final data clusters, k, may be fixed at one greater than the maximum number of clusters in a plurality of preliminary data clusters. In some embodiments, generating final data dusters 310 may include generating updated data clusters using one or more updated embedding network layers. In some embodiments, final data clusters 310 may include an updated data cluster generated by an updated embedding network layer. In some embodiments, final data clusters 310 may include a number of dimensions that is greater than the number of dimensions of one or more of preliminary data clusters 306 a, 306 b, 306 c, and/or 306 d. In some embodiments, final data clusters 310 may include a number of dimensions equal to n times a number of dimensions of one or more preliminary data clusters, where n may be a number of embedding network layers. As an example, an embedding network may have 5 layers (n=5), data 302 may and preliminary data clusters 306 a, 306 b, 306 c, and/or 306 d, may have three-dimensions, and final data clusters may have 15 dimensions (i.e., five layers times three dimensions).

In some embodiments generating final data clusters 310 may include repeatedly updating one or more embedding network layers until a performance metric of the one or more embedding network layers is satisfied. During individual rounds of training of an embedding network layer, meta-clustering model 308 may determine a number of clusters and train the embedding network layer based on the determined number of clusters (e.g., by specifying the number of clusters as a model parameter of the embedding network layer). In this way, meta-clustering model 308 may be trained to accept one or more preliminary clusters, generate a data map, and quickly converge on an optimal solution by determining an optimal number of clusters. Accordingly, in subsequent implementations, a trained meta-clustering model 308 may quickly and efficiently generate accurate final data clusters 310.

FIG. 4 illustrates method 400 for clustering data using a meta-clustering model, consistent with disclosed embodiments. As described above in reference to FIG. 3, method 400 may include using a plurality of embedding network layers 304 a, 304 b, 304 c, 304 d, and 304 n to classify and cluster data 302.

For example, a performance metric may be based on a measure of intra-cluster variance as compared to an inter-cluster variance in clustered data. A ratio of intra-cluster variance to inter-cluster may indicate how well an embedding network layer classifies data. A high ratio may indicate inaccurate data classification, while a low ratio may indicate accurate data classification. The performance metric at step 710 may be based on a plurality of individual performance metrics associated with individual embedding network layers (e.g., an average, a maximum of a performance metrics etc.). A performance metric at step 710 may be based on a comparison of the number of clusters generated by a plurality of embedding network layers (e.g., a variance, a percent agreement. etc.). A high variance or low percent agreement may indicate that inaccurate data classification, while a low variance or high percent agreement may indicate accurate data classification. A performance metric at step 710 may be based on, a k-means algorithm, a k-medoids algorithm, an elbow method, an X-means clustering method, an information criterion approach, a silhouette method, a cross-validation method, a method based on a kernel matrix, and/or any other methods of determining a number of clusters in data.

In some embodiments, a meta-clustering model determines a performance criterion at step 710. In some embodiments, a performance criterion may be a threshold based on one or more performance metrics of embedding network layers. A threshold may be based on an average or any other statistical measure of one or more performance metrics of embedding network layers. For example, a performance criterion at step 710 may be based on a minimum performance metric (e.g., the performance criterion may include determining whether at least one embedding network layer meets a minimum performance metric).

At step 712, data-clustering system 102 may determine whether to add an embedding network layer, consistent with disclosed embodiments. Determining at step 712 may be based on a performance criterion (e.g., a performance criterion of step 710). For example, if the performance criterion indicates disagreement or inaccurate classifications among the plurality of embedding network layers, data-clustering system 102 may determine to add an embedding layer. Conversely, if the performance criterion indicates agreement or accurate classification data-clustering system 102 may determine to not add an embedding layer. In some embodiments, determining at step 712 may be based on a predetermined number of network layers. Determining at step 712 may be based on an input (e.g., a manual input received via interface 522 and/or an input received from client device 110). Determining at step 712 may be based on data received at step 702 (e.g a list of embedding network layer identifiers).

As shown, data-clustering system 102 may repeat steps 604 through 610 if data-clustering system 102 determines to add another embedding network layer (i.e., if the determination at step 712 is “yes”). Alternatively, data-clustering system 102 may proceed to step 714 if data-clustering system 102 determines not to add another embedding network layer (i.e., if the determination at step 712 is “no”).
